Geometry of Lithium-Ion Battery Pack || CFD Simulation || Thermal Analysis

[@김동완-k5r]

Thanks for useful video for simulating li-ion battery pack. I'd like to analyze air cooling of battery pack consist of 70s 6p 21700 cell using MSMD model. But, there's no suitable guide for it. So could you make video or some advice for it please?

[@FrontiersInCFD]

Will do !

Thanks for a wonderfully and patiently explained video. I want to model a single 18650 cell with heat generation and natural convection alone. But while running the simulations, rather than converging, static temperature of my battery is rising suddenly after increasing the iterations. so what should I do ? how can I decide on optimal number of time steps?

[@FrontiersInCFD]

Select suitable mesh size and accordingly select time step size.

[@arjunprasanthU]

@@FrontiersInCFDDo you mean to say that Courant number be considered ?
If so what should be the fluid velocity since its natural convection ?

[@FrontiersInCFD]

Velocity is difficult to change as per flow however we can change mesh size and time step size

Useful video sir thanks

Welcome

Sir ,Is there any course regarding simulation of batteries only?

What is the meaning of reference zone?

[@FrontiersInCFD]

If fluid is flowing from inlet to outlet for the flow reference zone is fluid

Great Work

[@FrontiersInCFD]

Thanks

[@tharathankaraj1950]

Sir ,thank you for this video.Can we do simulation using one cell of battery?

[@FrontiersInCFD]

Yes it can be done. Even it will take less time for simulation as compared to this

[@tharathankaraj1950]

Thank you sir

[@sriharshajasti6245]

how can we change the battery nature from Li to NCM?

[@FrontiersInCFD]

Change material

[@bharathvislavath4414]

what should be the boundary conditions if air has to pass over the battery pack (IP67 Battery pack)? Anybody please

[@FrontiersInCFD]

select air as working fluid during material selection define the fluid zone for air

Thank you

Sir reference paper of this simulation ??

[@FrontiersInCFD]

received as requirement
